When can I take my new car on the highway?

After the completion of the initial磨合期 or first service (usually 3000 kilometers or 3 months), it is recommended to take your new car on the highway. It is also advisable to run your car at a speed of up to 180 km/h for about 10 minutes, followed by a slow and steady speed for another 10 minutes, before undergoing your first service. This will help to remove any debris and dirt that may have accumulated during the磨合期 and ensure a clean working environment for your engine.

Your new car can generally go on the highway as soon as you buy it, even without completing the initial磨合期. However, it is important to note that the minimum speed on the highway is 60 km/h.

The importance of a proper磨合期 cannot be overstated as it can have a significant impact on your car's longevity, safety, and efficiency. The typical磨合期 for most cars is 1,000 to 2,500 kilometers, with longer periods for imported cars, ranging from 1,500 to 3,000 kilometers. The three stages of the磨合期 are: the early 100 km, the initial 200 km, and the formation of a protective oxide layer at 3,000 km. If you do decide to go on the highway, your car can still run, but you need to adjust the speed and engine speed. For most cars, the speed should not exceed 80 km/h for the first 500 km, and the engine speed should not exceed 3000 rpm for the first 3000 km. After that, you can safely and confidently drive your car.
